[q] downgrade from official 4.3 xxuemk4 n7100 - Galaxy Note II Q&A, Help & Troubleshooting

Hello friends I need a little help in downgrading my N7100
I updated my note 2 to the latest official update 4.3 MK4 by downloading it from samfirmware. I installed it n it was working good. Next I tried rooting it with the procedure on this page http://www.ibtimes.co.uk/articles/5...e2-n7100-root-android43-xxuemk4-jellybean.htm
which was by CF AUTO ROOT method. The superuser app was injected in it but knox prevented itfrom running everytime. I tried it twice but invain. So I wasn't successful in rooting it n I'm running my phone without root n the bootloader now shows that the warranty is void .(.knox is stuck in there). I tried downgrading it to official 4.1.2 by odin but it doesn't go through n I had to flash official 4.3 again.
I need help my friends.. if anybody can tell me how to Reber back to 4.1.2 or if I can root my official 4.3
Please help me

Correct. However you can root 4.3.
All the info you need is already on forum if you use the search button. If you had bothered to do research before upgrading you would have already known about knox/bootloader.

Downgrading from 4.3
Hi, I flashed DN3 and I flashed MJ5 bootloader. I flashed WanamLite MK4 V4.2 Android 4.3 previously too. Is it possible for me to downgrade? I need to restore to factory setting since I'm going to send my phone for warranty.

I am newbee, can you please explain me how to downgrade from XXUEMK4 (India) to MJ5 bootloader. Please explain what is DN3 and how to flash it.

DN^is a rom, ditto note.. It has note 3 features. Like wanam or phoenix or dr.ketan's custom rom..
you can download it from the forum. just look for it.. And you can flash it with a custom recovery like philz touch or twrp..
This is all I am assuming that you know how to root and you have any version of any custom recovery.
If not, you can read dr. ketan's tutorial in the forum..

I'm not sure about that mate. I was told downloadable. But my downgrade fail for unknown reason. So I decided to flash stock 4.3, and the process fail too. I'm not sure if it's Windows 8, or it's my cable because everything goes fine with Windows 7. Then I flash again at Windows 8, everything turn to be fine. So I guess it's my cable and charger port issue. I will not downgrade to 4.1.2 since I just realize that my warranty expired 3 days ago.

The bootloader is stuck to new Knox so I advise to try to flash through Odin any room that have no bootloader in it. that means any room included stock. every attempt to flash bootloader will fail unles someone develop a method to enable us to do that
In regards with root.. after you have used CF method you must install SuperSu from market and that will bypass Knox in disable super user because come from a normal channel

thanks for quick reply.... i am currently on mk4 and have triggered the knox by using old method of root..... i tried to flash only mj5 bootloader bt it failed.... i need complete mj5 rom so that i can use dr. keten's method to make the bootloader knox free and then downgrade to 4.1.2....
http://forum.xda-developers.com/showthread.php?t=2500823
The thread you are posted writed before mk4 and is for upgrade from mi6 or 4.1.2 not downgrade. Read this thread
http://forum.xda-developers.com/showthread.php?t=2531965
Anyway if you can't flash mj5 bootloader (this is happening because you try to downgrade) also and all rom to try will be the same. Ask drketan if you can try his fix at your bootloader and how to downgrade, if is possible.

lets start from basics.... since i am able to flash 4.3 mk4 rom as many times , so i can also flash 4.3 mj5 rom easily( i am not downgrading here )... after that by applying patch to mj5 bootloader i can make it knox free and since dr. ketan has posted in his comment that yes it is possible to downgrade after applying patch to mj5 boot loader .. so this is what i am thinking of..
plzz tell is method possible for me? if yes where can i find mj5 rom link...
thank u in advance
don't waste your time..its not possible to change the bootloader once you flash official 4.3.
rom and bootloader is different thing !!
btw, since your knox already triggered you can not flash anything beside official 4.3..odin will failed

N7100xxuemj5
hello great members, during my search on this N7100XXUEMJ5 to downgrade the 4.3, i found a reply that if i am on an official 4.3 and tried to odin N7100XXUEMJ5 it will not be considered as a downgrade and it will be accepted, it was not clear if the Knox was triggered or not will matter.
I would like to try it myself, but all the online links for N7100XXUEMJ5 are like disappeared i am searching for days now, all i can find is a cwm flashable rom and from my understanding this will not include the bootloader, i will need the odin version, and will be very grateful if someone shared it or uploaded it
what makes me feel it will work is that these links or copies were not disappeared by themselves so it may be the only backdoor, that is why it is hidden looool.
Also, if i want to de-trigger the knox, without removing it, is there away ? as per my readings, it has been done in a few sec in samsung shop (not sure of it)

How Do I Root On 4.3 Official Firmware Without Voiding Knox?

Hey,
Flashed to 4.3 official yesterday and I now want the DN3 ROM. I saw a KNOW WARRANTY option and thought I wont root till I know what this is.
Is it safe for me to root? All I want to do is root get CWM then flash DN3 and I'll be set.
If it is safe to root, can you post a link to a guide and if it isn't any hassle a link to get CWM as when I tried to get it, it never loaded up properly and wouldn't install the DN3 from my zip (When I was on 4.1.2)
All help will be appreciated

As long as you have not done anything to trip it yet, flash DN3 bootloader, with your rom and you should be free of knox right?

For a 4.3 ROM, you need to install 4.3 bootloaders. Are there any drawbacks?

I'm considering upgrading to a 4.3 rom from 4.1.2 and I've learned that a stock image of 4.3 must be flashed first (thorugh Odin?) to update the bootloader to 4.3.
Is there any drawback to upgrading? Will I still be able to flash 4.1.2 roms using the 4.3 bootloader? Will I be able to downgrade to the 4.1.2 bootloader (should the need arise)?
Side question: is Odin the only way to update the bootloader? Can it be flashed through TWRP?

You'll have Knox. (Stock) which locks u down cause u can't downgrade and by rooting, you're going for a un-reset-able Knox Warranty Void trigger. Downgrading bootloader is impossible as of now, but flashing ROMs should be possible. (Should, not damn sure)
Side Answer: don't think so. Just flash stock 4.3 through TWRP and u should be good to go.

I'm running 4.3 JediMasterX2 with old bootloader and devil kernel and everything seems to be running fine. There was a very informative post made recently they gave a clean and simple explication of pros and cons to bootloader update. I'll try to locate and post a link but long story short, it's in your best interest not to update bootloader if you don't have to.

Please don't do the official update and get yourself locked down like many of us have. I have flashed many 4.3 roms and they worked fine. Got a new phone and did the official update and now I cannot send this device in for warranty because of the KNOX flash counter.

[Q] Please help me. Knox!

Hello guys!!!
I have a Galaxy Note II N7100 for the past 1 year. I recently installed Hurricane v 8 rom which is based on 4.3 firmware.As I was using it, I realized the RAM was increasing up to 1.3 GB, the only thing that could fix it was to reboot the phone. Later I watched a youtube review of a Note II with an official 4.3 installed and the RAM was about 600 MB on that persons phone. So I went ahead and downloaded a 4.3 firmware N7100DDUEML4 from sammobile.com. After the installation via Odin I boot the phone and it was fine. I read a few articles on how I can root the 4.3 firmware with CF Autoroot and did it as it should be done. After the reboot, Knox blocked the SU and the KNOX flag went to 0x1. After all this I decided to install Philz Recovery via Odin and got access to recovery. My plan was to recover my Hurricane Rom that I previously backed up. After Philz recovery restored the Hurricane Rom, I got stack on Boot Screen. Because Knox is flagged 0x1 I can't install any firmware via Odin anymore. So the next step I did is to restore my phone via Kies. I managed to successfully restore it and now I have a 4.3 firmware N7100XXUEMK9 firmware and Android Status As Enforcing. How can I get root access with this firmware and what should I do with Knox flag 0x1?
Thank you in advance guys!!!
The SafeRoot exploit has been confirmed working for N7100 too (check here), but it can't help to reverse Knox flag 0x1. Try it out. it should work. Anyway, why bother warranty after 12 months?

Thank you so much for your reply, yeah it is true but it is not that I am worried about the warranty, I want to revert back to a different rom and patch a bootloader so I can install custom firmwares.MJ5 bootloader patch doesn't work for me. Is it possible at this time to patch this MK9 or it is still unsolved issue? Thank you once again for your reply.
I have read a lot of posts & make sure I understand the details before I upgrade to v4.3. The far too many failures for upgrades that I've ever seen prior to v4.3 make me more conscious than ever. I'm on MJ5 bootloader & successfully loaded two different custom ROMs without any problem. I suggest you to do more reading in this forums prior to the upgrade. If you're on bootloader newer than MJ5 then I would suggest to stay with the bootloader & root it with the Safeboot method then clean up the KNOX crap. It should work great after the upgrade, root & clean up. cheers.

You got two options either root your phone while being on 4.1.2 or upgrade to official Indian 4.4.2 and then root it.Ofcourse once you root your current 4.1.2 you can try custom 4.4 ROM and if you don't like it you can go back to 4.1.2 or flash a 4.3 custom ROM. To root your 4.1.2 rom read this guide.If you decide to upgrade to 4.4.2 Indian firmware download it from here.
To flash the 4.4.2 ROM on your phone download it from the above link(there are 3 links where the ROM is uploaded) ,use any of the links and download the zip file,extract it you'll get a tar file,put your phone into download mode ,open odin v3.09 on pc and flash the official stock rom by checking the AP tab on odin.You can find tutorials on youtube on how to use odin to flash official stock firmware so just look them up if you need it.Once you flash stock ROM you can root your phone via this guide.
Okay so now things to remember.If you root your 4.1.2 ROM and want to try 4.3 or 4.4 custom ROM you need to flash MJ5 bootloader in order to have working wifi.Bootloader is flashed directly on your mother board and it cannot be downgraded only be upgraded.MJ5 is the last 4.3 bootloader which is KNOX free(what is knox ,blah blah,you can read about it on google).Advantage of MJ5 is you can try 4.1.2/4.3/4.4.2 rom and your warranty and knox remain intact but if you upgrade to official 4.3 or 4.4.2 ROM you'll be on knoxed bootlooader which means you cannot downgrade to 4.1.2 anymore plus rooting a phone with knoxed bootloader will trigger knox 0x1 and your warranty if any will be void (no way yet to reset Knox).So if you have warranty on your phone then my advise is root your 4.1.2 Rom,download any 4.3 or 4.4.2 custom ROM,you wont have wifi working then flash the MJ5 bootloader from here and read this post on how to flash bootloader.
I know it's a lot of info to you but your best guide is self reading from the above links i hooked you up with.Also read comments from people cause that's how I learned I read and read a lot before i jumped the rooting bandwagon cause wanted to make sure i don't brick my phone. Ofcourse whenever in doubt STOP RIGHT THERE and ask us.Dont attempt things that you are not sure of.Good luck.
Thanks for the help

Okay so now things to remember.If you root your 4.1.2 ROM and want to try 4.3 or 4.4 custom ROM you need to flash MJ5 bootloader in order to have working wifi.Bootloader is flashed directly on your mother board and it cannot be downgraded only be upgraded.MJ5 is the last 4.3 bootloader which is KNOX free(what is knox ,blah blah,you can read about it on google).Advantage of MJ5 is you can try 4.1.2/4.3/4.4.2 rom and your warranty and knox remain intact but if you upgrade to official 4.3 or 4.4.2 ROM you'll be on knoxed bootlooader which means you cannot downgrade to 4.1.2 anymore plus rooting a phone with knoxed bootloader will trigger knox 0x1 and your warranty if any will be void (no way yet to reset Knox).So if you have warranty on your phone then my advise is root your 4.1.2 Rom,download any 4.3 or 4.4.2 custom ROM,you wont have wifi working then flash the MJ5 bootloader from here and read this post on how to flash bootloader.
I know it's a lot of info to you but your best guide is self reading from the above links i hooked you up with.Also read comments from people cause that's how I learned I read and read a lot before i jumped the rooting bandwagon cause wanted to make sure i don't brick my phone. Ofcourse whenever in doubt STOP RIGHT THERE and ask us.Dont attempt things that you are not sure of.Good luck.

Wow that's a lot of info you provided there, thanks. I am not new to rooting as far it goes I have rooted and flashed many roms on my galaxy s advance and my micromax A87 before that. But note 2 was a flagship device so there are many complications that come along which got me confused. As for now, I have my rooted 4.1.2 stock rom along with cwm recovery flashed via rom manager. I am planning to flash either DN3 or the Xperia Z-ized rom. So my question is: do I have to flash mj5 bootloader to flash DN3 and xperia z-ized or can I directly flash it from cwm (with factory reset and necessary wipes of course)?
BTW, I have heard that knox is a security application that prohibits rooting on samsung phones. It also had a reward for $18k for those who can bypass the knox on the S5 and root it. If I am right, then I think I am fairly acquainted to knox.
Once again, thanks a lot for helping! Appreciate it

Since you are on stock 4.1.2 MJ5 is required for wifi to work.i learned 2 weeks ago that even mj5 is not required as previously thought by us at least not while flashing 4.4.2 TW rom.When you flash 4.4.2 custom ROM you wont have wifi working,then flash custom kernel like agni or nadia and wifi works flawlessly so one doesn't need to flash mj5 bootloader.I am not sure if this would work on 4.3 ROM you could try xperia z'd 4.3 custom ROM then flash a compatible 4.3 custom kernel and see if wifi works if it does you're set.This was new to most of us so I asked the person who told me about this how did he manage to do this and he told me apparently custom kernels have some sort of wifi drivers on them so when we flash custom kernels on 4.4.2 ROM wifi works but it wont work on stock kernel unless you upgrade to MJ5 and on stock kernel.MJ5 is safe to flash anyways since its knox free bootloader.
Actually 4.3 and 4.4.2 note 2 phones and others got knox on them but we found a way to disable knox after rooting our phone SuperSu disables it but knox is triggered to 0x1 and there's no way to reset KNOX since it's concerned with the motherboard of the phone which is the heart and soul of out note 2.So that bounty you might be talking about how to reset it perhaps.Even if they succeed in reversing it doesn't necessarily mean it would work on note 3 or note 2 cause of the phones being of different hardware .i don't know the technicalities of this.

Lurking around in xda and reading as much as I can and participating in discussions related to Knox.I was clueless to all this Knox and how it works.My previous phone was HTC HD2 so samsung note II was the first serious smartphone I owned so just wanted to be extra careful that I don't end up bricking my device so read and read and asked questions.
